Application led March 14, 1914. Serial No. 824,721.

To all whom t may concern:

Be it known that l, EDWARD TRIsT, a subject of the King of England,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, Vhave invented certain new and useful Improvements in GasStoves and Ranges, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to gas stoves and ranges, and has for its objectto provide a gas stove or range, with means, in a manner as hereinafterset forth, for retarding the flow of the heating units, under suchcircumstances increasing the efliciency of the stove.

Further objects of the invention are to provide a gas stove or rangewhich is simple in its construction and arrangement, strong, durable,efficient and convenient in its use, readily set up and comparativelyinexpensive to manufacture.

With the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the sco e of the claim hereuntoappended.

the drawings wherein like reference characters denote correspondingparts throughout the several views:-Figure 1 is an elevation, brokenaway, of a gas range in accordance with this invention. Fig. 2 is a sideview, partly in section, with parts broken away to show the structure ofa gas range in accordance with this invention.

Referring to the drawings in detail, 3 denotes the body portion of a gasrange, and which has its bottom 4 provided with air inlet openings 5.Within the body portion 3 is arranged a rectangular shell 6 forming anoven 7 which is closed at its rear by the back wall 8 of the bodyportion 3, and is closed at its front by a door 9, which is hinged asat10, to the front wall 11 of the body portion 3. Arranged forwardly ofthe front of the body portion 3, near the top thereof, is a gas supplypipe 12, which is provided with valves 13 for controlling the supply ofgas to burners at the top of the range, and said pipe 12 has a downwardextension 14, which communicates with a feed pipe 15; the latter has anextension 16, which opens into a gas and air mixer 17, carried ontheouter end of a burner tube 18, the latter having outlets 19, and thesaid tube is positioned between the bottom of the oven 7 and bottom l ofthe body portion 3. The foregoing elements are of lmown construction.

rihe shell 6 is of such size with respect to the body portion 3 to formheating spaces 19a- 2O at the sides of the shell, a heating space 21 atthe bottom of the shell, and a heating space 22 at the top of the shell.

Secured to the outer face of each side of the shell 6 is a series ofspaced heat retarders, and each of which consists of a plate 23 providedwith longitudinal flanges 25. One of the flanges is arranged above theother, and each of the flanges depend downwardly at an inclination. Theflanges are of the same length as the length of their respective plate,and each plate is of a length equal to the length of the shell, and isfiXedly secured to the shell by the hold-fast devices 26.

rfhe inner face of each of the sidewalls of the body portion 3 isprovided with a series of superposed spaced seats 27, and arranged ineach of said seats is the depending flange 28 of an upwardly inclinedstrip 29, which constitutes a heat retarder, and the said strips 29 arealternately disposed with respect to the flanges 25, and are so arrangedthat they are positioned centrally with respect to the flanges 25. Theflanges 25 extend at a greater inclination than the strips 29, and thesaid strips 29 are fiXedly secured in position by the holdfast devices30.

r[he flanges 25 upon one side of the shell 6 extend in an oppositedirection with respect to the flanges 25 upon the other side of theshell 6, and the strips 29 upon one side of the body portion 3 extend inan opposite directiodn with respect to the strips upon the other s1 e.

The flanges 25 and strips 29 retard the passage of the heat units asthey travel through the spaces 19g-20, under such conditions increasingthe e'iciency of the oven as the same is heated in a uniform manner,

due to the retarders, and further heated morequickly as the heat unitsdo not pass rapidly through the spaces 19a-20.

A stove of the class described comprising a body, a shell arrangedtherein in spaced relation to the side walls thereof, a plurality ofseats arranged in superposed relation to one another on the inner facesof the side wardly toward the aforesaid retarders to walls of said body,heat retarders formed of alternate the latter. 10 angular metal arrangedin the seats and hav- In testimony whereof I afiX my signature ingportions thereof projected upwardly in the presence of two witnesses.
